Batrain comes from the anime "Galactic Whirlwind Sasuraiger", which was produced
by Kokusai Eiga Sha, TV Tokyo, and aired from April 1983 to January 1984.

The main mecha of the show was called Batrain. Takatoku toys put out several
different toys of this character in the early 80s. The toy is a very solid
mix of die cast and plastic. The die cast content is limited to two swing bars
in the waist. Transformation is simple, but involves removal of the arms.

Batrain
included missile firing
fists,
a
gun,
and missiles.

The toy pictured here may be a bootleg. I can't find any markings on it anywhere,
but I have not had the opportunity to examine another one to compare. The pictured
toy is missing the gun, missiles, and a small green ring that goes around the
yellow stack.
